Longterm review: NOS

Every now and again, my curiousity gets the better of me on the subject of NOS.

I'd like some opions and reviews as to the longterm affects of NO2 from anyone with forced induction and a stock bottom end......

Is the bottle still considered a NO-NO when used in conjuction with forced induction...?

Seems to me that all the brainiacs were predicting disastrous results.... I know that a number of guys running NO2 have gone kablooey... But I'm curious as to whather or not it was due to too big a shot of juice or whether FI and juice simply don't mix on a stock lower end....

Is a 50 shot still too hot....
When a Paxton blower is what I've got..?

Thanks, guys 'n' girls....

Django

This guy here, locally has a Sprayed/Roe SC 96 GTS. Supposedly a stock bottom end, stock long block at that. He's running meth injection also. I have no clue what shot he runs, I've never heard him disclose it.

Here's a vid of the car: http://videos.streetfire.net/search/...e306fcad75.htm

(Please, lets call it nitrous from now on or even NO2. NOS® is a brand name and reminds me of ricers in a bad way! )

Well Tim, let me see if I can help out a little.

I'm going to start with a non-boosted engine and then just explain the difference in your situation.

When you inject Nitrous (better Roz? ) it has no affect on the cylinder pressures during the intake stroke. All it is doing is adding more oxygen and fuel, which is basically what a FI system does.

However, it greatly increases the cylinder pressure during combustion and the power stroke as it is burning that extra oxygen/fuel mixture. This is the increased stress that the engine components are subjected to. Make sense so far?

Okay, now with a Paxton system such as yours you are also increasing the cylinder pressure during the compression stroke as you have forced more air/fuel mixture into the cylinder. This also increases the cylinder pressure during combustion and the power stroke as it is burning that extra air/fuel mixture. So what happens in the FI engine is a combination of a FI and NA engine. The cylinder pressure is the same on the compression stroke, but the cylinder pressure during combustion and the power stroke is a combination of the extra air/fuel mixture from the FI system and the oxygen/fuel from the Nitrous system.

Does that help?

I really tried to dumb this down so that even Mikey could understand it if he stops by this thread.

Wouldn't colder plugs and meth injection help lower the compression?
